AMANDUS C. ROESSLEB, OF MINEOLA, AD WILLIAM A. ARMINGTON, OF NEW YORK,N. Y., ASSIGNORS T O B AY STATE GAS COMPANY (DELAWARE)- A CORPORATION OFDELAWARE.

To all whom t may concern.' I

Be it known that we, AMANDUS C. RoEss` Y LER, a subject of the King ofGreat Britain and Ireland, formerly of London, England, and now aresident of Mineola, Nassau county, and State 'of New York,and TIL- LIAMA. ARMINGTON, a citizen of the United States, and resident of thelborough otI county of Kings', city and State' Brooklyn' of New JYork,`have invented certain new and useful Improvements in Gas Systems, ofwhich the following is a specification.

Our invention relates particularly to those gas systems wherein a pilotlight or pilot, as it is called, is used for igniting the burner.

To be effective in lighting the burner, it

has been necessary heretofore to place the" 'pilot to throw a flamedirectly-"against'the this cross tire against the already heatedburner.Where the burner is in the form of an inverted mantle, itwill be evidentthat mantle will have a very injurious ee'ctl.,

The principal object of our invention is to overcome these variousobjections.

To this end our invention consists in placing the pilot a considerabledistance away from the burner lso as not .to be .injured by the heat vofthe burner, and in providing l so as totdirect the iame issuingtherefrom,

ltoward the; burner, and it is furthermore disposed far enough away'fromthe burner so means for Aadmitting an excessive flow of fuel to thepilot just as the burner is turned y on, so that under this greaterimpulse the .flame from the pilot will bridge the distance l .causeignition between pilot and burner and at the burner.

Ina preferred form the :means for`con: trolling the flow of gas to thepilot consistsl of certain valve'mechanism embodying in part a rotaryvvalve body Ahaving passages j which when the. valve body is operated toturn on flow Ato the burner, will permit an excessive flow to the pilot,and will, as the flow to the burner is turned all the way on, finallycut 0E the pilot entirely.

Another feat-ure of our invention, when the same is used in connection-with a preseas SYSTEM. Y

means for simultaneously cutting off both the flow of the air and thegas. The means for accomplishing this purpose may be a part of that samevalve mechanism which controls the pilot.

Various other objects and features of our linvention will appear as thespecification proceeds.

Wye have illustrated in the accompanying drawings, a preferredembodiment of our invention, but we would have it understood thatvarious changes and modifications may be made therein without departing'from'the spirit and scope of theA invention.

Fig. 3 is an enlarged sectional view of the valve mechanism, this viewbeing taken .With

the rotary valve body in the position indi- `cated in Fig. 4. Figs.4:,*5- and Aare detail sectional views illustrating the operation of thevalve. Fig. 7 is a detail view of a slight modification of the valvemechanism. y

Like reference characters have beenused to designate like partsthroughout the several views. l V L For purposes of illustra-tion. "-wehave shown our-inventionl as applied to a pressure-gas'sy'stem in whichthe burner 1receives a supply of mixed air and gas from 'the air and gasconduits 2 and 3 respectively the gas and air-being properly comminglodin amixi chamber 4, before `reaching the burner. T e .pilot 5 is, asshown, disposed asnot to -loe injured by the heat of the burner; This'distance may vary but it is y preferablysuchfthat when somewhat morethan the usual flow of gas is admitted to the pilot, the iiame from thepilot will just reach to the burner. The pilot is supplied'with gasthroughl a pipe ortube 6. v

In its preferred form t'he valve mechanism consists of` a valve 'casing7, with a valve body 8, rotati'vely engaged therein.' f The extending inone direction only from the opposite end of the main passage, wherebywhen the Valve body is rotated to bring the main passage into a'linementwith thefconduit,`-` an` additional volumeof-gas will rst" besupplied tothe pilot, after which ther pilotv connect-ion will lbe closed.
